Falkland Islands (Islas Malvinas) in the Permo-Carboniferous focuses on the sedimentology of the Hells Kitchen Member of the Port Sussex Formation in East Falkland (Las Malvinas). This member comprises deposits documenting the switch from Icehouse to Greenhouse conditions in a fragment of the Gondwana supercontinent during the Permian. Sedimentary logging, X-Ray Fluorescence data and reflectance data measured over this interval will be presented in detail in Falkland Islands (Islas Malvinas) in the Permo-Carboniferous and used both to support a facies evaluation and an investigation into the orbital control of climate at this time.
